4.3 Length Measuring
Before starting to measure it is important to check the
calibration of the measuring arm. This is done by compressing
the arm altogether and pushing the ON/0 button for at least
three seconds so that the display goes off. With the measuring
arm still compressed push the ON/0 button and the digital
number 900 (900mm) will appear.
The measuring tool is now calibrated and will start measuring
from 900 mm.
If during measuring operations any doubt exists about the
calibration of the measuring arm, repeat the above procedure.
1.
Read the length dimension between the magnetic
attachment and the measuring point to be measured
according to the data sheet.
2.
Read the height dimension given on the data sheet and
select a suitable height measuring rod and adaptor
(socket).
3.
Push the height measuring rod and adaptor into the
measuring tool and set it to the height dimension given
on the data sheet.
4.
Mount the magnetic attachment in the intended
attachment point. Pull out and adjust the measuring
tool so that the selected measurement point can be
reached.
(It can be advantageous here to use the hold feature to
freeze the measurement value, especially if it is difficult
to see the display while measuring. Press the
HOLD
button briefly to freeze the measurement value. To
return, press the
HOLD
button again briefly.)
5.
Read the measuring arm’s display and compare the
length measurement value with the value on the data
sheet.
(It can be advantageous here to enter the measured
value in the data sheet table in order to create a
before or after report.)
